Circular Saw Blade Types
There are various types of circular saw blades to choose from, each designed for specific purposes. The blade type will influence the number of teeth per inch and how they are arranged, which will have a significant impact on whether or not a blade is suitable for a particular task.
Flat Top Grind (FTG)
FTG blades have teeth that sit square to the saw plate. They cut through wood, much like a chisel. They rip the wood perpendicular to the grain, which means they won’t produce smooth cuts.
Pros
- Great for rip cuts
- Hard wearing
- Cuts quickly
Cons
- Only suitable for rip cuts
Alternate Top Bevel (ATB)
The teeth of an ATB blade point in alternating directions and they are designed primarily to shear wood. These are all-purpose blades that will be suitable for general cutting jobs.
Pros
- General-purpose cutting
- Very versatile
- Great for joinery
Cons
- Don’t excel in any area
- Not suitable for refined woodworking
High-Angle Alternative Bevel (HI-ATB)
These blades are a variation of the ATB design, with a different bevel angle. HI-ATB blades have a bevel angle of between 25 and 38 degrees, compared to 10 to 20 degrees for ATB blades.
High-angle blades are excellent for cutting veneers and other sheet-engineered wood used in cabinet making and bespoke furniture.
Pros
- Great for engineered wood
- Cuts smooth lines
- No chipping
- Suitable for laminate
Cons
- Fragile
- Prone to wear and tear
Triple-Chip Grind (TCG)
TCG blades have alternating chamfered and raker teeth. The chamfered teeth rough cut, while the raker teeth clean up the cut. This is the right blade to use for sawing plastic laminate and Corian, as well as non-ferrous metals such as brass and aluminum.
Pros
- Cuts a wide range of materials
- Makes neat cuts
Cons
- Better for materials other than wood
- Not for general cutting
How To Choose a Circular Saw Blade
There are several important factors to consider that will help you choose the right circular saw blade. Some of these elements might be more important than others, depending on the specific task you need the blade for.
Size of Blade
Circular saw blade sizes are usually 8, 10, or 12 inches. 10 and 12 are far more common but 8-inch mini circular saws are growing in popularity, as are even smaller blades. Some measure just 4.5 inches.
Top Tip
Type of Saw
The type of saw you own will determine which kind of blade you need. Make sure the arbor fits the shaft of the saw. If you have a mismatched blade and saw, the blade might tip during use, which could ruin whatever you are working on.
Teeth
How many teeth a circular saw blade has will determine how it can be used. As a general rule, the higher the number of teeth per inch, the smoother the cut will be. This means saws with a high TPI are better suited to cutting tough materials such as sheet metal and hardwood.
If the tooth count is lower, the blade will be better for softer materials where cuts can be less precise.
How Many Teeth Do You Need on a Circular Saw Blade?
The number of teeth you need will be determined by the material you are cutting. If you are cutting softwood or similar materials, fewer teeth will be better. Harder materials will require greater tooth density.
This chart should help you :
| Type of Blade | TPI | Total Number of Teeth (Average) | Suitable For |
| Coarse | 3 to 8 | 40 to 60 | Lumber, hardwood, softwood, MDF |
| Medium | 8 to 18 | 60 to 80 | Lumber, hardwood, softwood, MDF, plyboard, sheet metals |
| Fine | 18 to 32 | 80 to 120 | Plyboard, frames, sheet material, non-ferrous metal |
Quick Note
Kerf
Kerf refers to the width of the blade, which is reflected in the thickness of the cut it makes and how much material it wastes. A full kerf has an edge measuring 0.125 inches, whereas a thin kerf is 0.094 inches.
Full kerfs are more durable and better suited to cutting tougher materials. However, a blade with full kerf places more stress on the saw motor. If the motor is underpowered, this can lead to it overheating and potentially burning out.
A thin kerf suits finer detail work and wastes less material. They also require less power to use, so the motor won’t need to work as hard, which will protect your saw. The downside of these blades is that they wear out more quickly due to having thinner edges.
Blade Coating
Many popular brands including Freud and Bosch coat their blades in special non-stick solutions. These coatings reduce friction and help the blade slice through the material more easily. By preventing binding, they also reduce the risk of kickbacks, which can be major hazards when using circular saws.
Blade Material
Carbon Steel
Carbon steel blades are well suited to cutting soft materials and plastics. They are the cheapest blades you can buy but they will dull quickly due to their soft teeth. This means they won’t last long if you use them frequently. There is an upside to their softness, however, as they are flexible, which means they are less likely to snap during use.
High-Speed Steel (HSS)
Compared to carbon steel blades, high-speed steel is far more durable. These blades retain their cutting edge for longer and have better heat resistance, which means they won’t need to be replaced as frequently.
Typically, these blades can withstand temperatures of up to 600 degrees centigrade and score between 62 and 66 on the Rockwell Hardness Scale. As they are designed for use at higher speeds, HSS blades will cut through MDF and hardwood with ease.
Cobalt Steel Blades
Cobalt steel is an alloy containing between 5% and 8% cobalt. Blades made of it are robust and can withstand even more punishment than HSS blades. Cobalt steel blades can also cope with very high temperatures, which makes them resistant to dulling during even heavy-duty work.
These blades outlast high-speed steel blades and far outperform carbon steel blades. Their only downside is that they are brittle and prone to snapping if they aren’t used carefully.
Carbide-Tipped Blades
Carbide-tipped blades are more expensive than other types because they are extremely durable. They typically score 65 to 80 on the Rockwell Hardness Scale, which means they are among the hardest-wearing blades you can buy.
They will cut through sheet metal, aluminum, and even steel. However, like cobalt steel, carbide-tipped blades can be brittle so you will need to use them carefully.
Job Suitability
Carbon steel blades are best used for cutting soft materials such as softwood and lumber. It is possible to buy carbon steel blades that can cut sheet metal and other non-ferrous metals, but the teeth usually dull very quickly.
Carbon steel blades are characterized by having lower tooth counts, a sign that they are best suited to less intense jobs.
Best For: Rip cuts, crosscuts, lumber, softwood, plastic, soft sheet metal.
High-speed steel and cobalt steel are both very durable. They will cut through wood, steel, aluminum, plastics, and composites such as MDF. These blades have improved heat resistance and retain their sharpness for longer, so they are both popular choices.
Cobalt steel and high-speed blades usually have higher TPIs that help them cut through harder materials. This also results in a smoother finish.
Best For: Crosscuts, hardwood, MDF, metal, plastic, smoother finishes.
Carbide-tipped blades are the most durable type you can buy and are used to cut the hardest materials, even concrete blocks. These teeth rarely require maintenance but, when they do, you will always be able to restore them to their original sharpness.
Best For: Crosscuts, hardwood, plastic, metal, concrete blocks, smooth finishes.
Who Makes the Best Circular Saw Blades?
Bosch
Robert Bosch founded the “Workshop for Precision Mechanics and Electrical Engineering” in Stuttgart in Germany in 1886. By 1901, Bosch had transitioned into automotive supplies and built a reputation for constant innovation (1).
Today, Bosch is one of the leading manufacturers of tools and accessories around the world, with hundreds of thousands of employees.
DeWALT
Raymond DeWalt, a sawmill supervisor, invented the radial arm saw in 1922 with the goal of improving productivity. In the century since, his company has grown to become one of the biggest global tool manufacturers (2). DeWALT is held in high regard as an innovator of high-quality tools and accessories.
Makita
Makita was founded in 1915 as a motor sales, repair, and servicing company. By 1958, Makita had introduced the first electric planer and shifted its focus to manufacturing power tools (3). Today, Makita is a global brand and is known for its high quality and reliability.

How To Change a Circular Saw Blade
1. Disconnect the Power
Before proceeding, make sure you disconnect the power supply from the wall socket or remove the saw’s battery.
2. Engage the Locking Mechanism
Press down on the arbor lock button, then rotate the blade until it engages the locking mechanism.
3. Use the Blade Wrench
Use the blade wrench to remove the arbor nut. To loosen the nut, turn the wrench in the same direction that the blade usually spins.
4. Retract the Blade Guard
Retract the blade guard and carefully remove the old blade. Even if the teeth aren’t cutting effectively, there will still be sharp edges that could injure you.
5. Insert the New Blade
Put the new blade onto the saw’s arbor, making sure the teeth are facing the correct way to cut effectively. There should be an arrow on the saw’s blade guard that will confirm whether or not you have inserted the blade properly.
6. Tighten the Arbor Nut
Tighten the arbor nut but be careful not to overtighten it. If you do, it will be far more difficult to loosen the next time you need to remove the blade.
You are now ready to plug your saw in and start using it.
How To Clean a Circular Saw Blade
Follow our guide to remove the blade. Once you have, place it in a bowl of warm soapy water. You can use detergent or an all-purpose cleaner if you prefer. Submerge the blade and leave it to soak for 5 to 10 minutes.
Grab a soft brush (an old toothbrush will work) and gently scrub any stubborn dirt or marks to remove them. Hold the blade by its center hole and gently shake it in the water to dislodge any remaining dirt.
Once the blade is clean, lift it out of the water and dry it with a soft, clean cloth. Make sure the blade is completely dry before you place it back into the saw or the moisture might cause corrosion and ultimately ruin your blade.
Again, follow our blade replacement guide to insert the blade back into the saw.
FAQs
How Long Should a Circular Saw Blade Last?
The longevity of a circular saw blade depends largely on the quality and frequency of usage. Generally speaking, high-quality blades can last between 12 and 120 hours of continuous use depending on how often it is used and the material it cuts.
For example, blades specifically designed for cutting hardwoods will need to be replaced more often than those designed for softer woods like pine.
With regular maintenance and proper storage, however, you can ensure that your circular saw blade lasts as long as possible.
Which Type of Circular Saw Blade Stays Sharp the Longest?
The type of circular saw blade that stays sharp the longest is usually the high-speed steel blade. This type of blade maintains its edge better than other blades due to its construction, which includes a thicker and harder steel alloy.
These blades are less vulnerable to heat, wear, and corrosion damage and therefore can stay sharper for longer periods. Using these types of blades may require more frequent sharpening sessions, but it will result in better cutting performance over the long run.
Is It Worth Sharpening Circular Saw Blades?
Sharpening a circular saw blade will not only help to improve its cutting performance but also extend its lifespan too. It can be done using either an abrasive wheel or a special file and it is relatively easy to learn with some practice.
Whilst sharpening blades may not always be necessary, it can save money in the long run and make cutting that much easier. It’s definitely worth a try if you want a way to keep your blades in top condition!
How Many Times Can You Sharpen a Circular Saw Blade?
A circular saw blade can be sharpened about three times before needing to be replaced but the quality of the blade determines the exact number.
With each sharpening session, however, it is important to note the amount of metal removed from the blades as this should not exceed 2 millimeters or there will be a risk of blade breakage.
A little maintenance here and there goes a long way in keeping your circular saw running smoothly!
